Ukusebenza ngokufanelekileyo kokufakwa kwe-interlayer ye-PCB yamanqanaba amaninzi

Kule post yebhlog, siza kuphonononga iindlela ezahlukeneyo kunye nezicwangciso zokuphumeza ukusebenza ngokugqibeleleyo kokugqumaPCBs zomaleko amaninzi.

Ii-PCB zeMultilayer zisetyenziswa ngokubanzi kwizixhobo zombane ezahlukeneyo ngenxa yokuxinana kwazo okuphezulu kunye noyilo oludityanisiweyo. Nangona kunjalo, inkalo ephambili yokuyila kunye nokuveliswa kwezi bhodi zeesekethe eziyinkimbinkimbi kukuqinisekisa ukuba iimpawu zabo zokugquma i-interlayer zihlangabezana neemfuno eziyimfuneko.

I-Insulation ibalulekile kwii-PCB zamanqanaba amaninzi njengoko ithintela ukuphazamiseka komqondiso kwaye iqinisekisa ukusebenza ngokufanelekileyo kwesekethe. Ukwaleka okulambathayo phakathi kweeleya kunokukhokelela ekuvuzeni komqondiso, ukudibana, kunye nokusilela kwesixhobo sombane ekugqibeleni. Ke ngoko, kubalulekile ukuqwalasela kwaye kuphunyezwe la manyathelo alandelayo ngexesha loyilo kunye nenkqubo yokuvelisa:

1. Khetha imathiriyeli efanelekileyo:

Ukukhethwa kwezinto ezisetyenziswa kwi-multilayer PCB isakhiwo kuchaphazela kakhulu iimpawu zayo zokugquma i-interlayer. Izixhobo zokugquma ezinje ngeprepreg kunye nezixhobo eziphambili kufuneka zibenombane wokuqhekeka okuphezulu, ukungaguquguquki kwedielectric ephantsi kunye nento ephantsi yokulahla. Ukongezelela, ukuqwalasela izinto eziphathekayo ezinokumelana nokufuma okuhle kunye nokuzinza kwe-thermal kubalulekile ukugcina iimpawu zokugquma ixesha elide.

2. Uyilo lweimpedance olulawulekayo:

Ulawulo olululo lwamanqanaba e-impedance kuyilo lwe-PCB ye-multilayer lubalulekile ekuqinisekiseni imfezeko yophawu olufanelekileyo kunye nokuphepha ukugqwetheka komqondiso. Ngokubala ngononophelo ububanzi bomkhondo, izithuba, kunye nobukhulu bomaleko, umngcipheko wokuvuza komqondiso ngenxa yokugquma okungafanelekanga unokuncitshiswa kakhulu. Finyelela amaxabiso achanekileyo kunye angaguquguqukiyo okuthintela kunye ne-impedance calculator kunye nemithetho yoyilo enikezwe yisoftware yokwenziwa kwePCB.

3. Ubunzima bomaleko wokugquma banele:

Ubukhulu bomaleko wokugquma phakathi kweeleya zobhedu ezimeleneyo zidlala indima ebalulekileyo ekuthinteleni ukuvuza kunye nokuphucula ukusebenza ngokubanzi kokugquma. Izikhokelo zoyilo zicebisa ukuba kugcinwe ubuncinci be-insulation ungqimba ukuthintela ukophuka kombane. Kubalulekile ukulungelelanisa ubukhulu ukuhlangabezana neemfuno zokugquma ngaphandle kokuchaphazela kakubi ukutyeba kunye nokuguquguquka kwePCB.

4. Ulungelelwaniso olululo kunye nobhaliso:

Ngexesha lokuhlamba, ukulungelelaniswa okuchanekileyo kunye nokubhaliswa phakathi kwe-core kunye ne-prepreg layers kufuneka kuqinisekiswe. Ukungahambi kakuhle okanye iimpazamo zokubhalisa zingakhokelela kwizithuba zomoya ezingalinganiyo okanye ubukhulu be-insulation, ekugqibeleni kuchaphazela ukusebenza kwe-interlayer insulation. Ukusebenzisa iisistim zolungelelwaniso ezizenzekelayo ezizenzekelayo kunokuphucula ngokubonakalayo ukuchaneka kunye nokuhambelana kwenkqubo yakho yokucoca.

5. Inkqubo yokuthambisa elawulwayo:

Inkqubo ye-lamination yinyathelo eliphambili kwimveliso ye-PCB eninzi, echaphazela ngokuthe ngqo ukusebenza kwe-interlayer insulation. Iiparamitha zolawulo lwenkqubo engqongqo efana noxinzelelo, ubushushu kunye nexesha kufuneka ziphunyezwe ukuze kuphunyezwe ukugqunyelelwa okufanayo kunye nokuthembekileyo kumanqanaba onke. Ukubeka iliso rhoqo kunye nokuqinisekiswa kwenkqubo ye-lamination iqinisekisa ukuhambelana komgangatho we-insulation kuyo yonke inkqubo yokuvelisa.

6. Ukuhlolwa kunye novavanyo:

Ukuqinisekisa ukuba ukusebenza kwe-interlayer insulation ye-PCBs yamanqanaba amaninzi ihlangabezana nemigangatho efunekayo, ukuhlolwa okungqongqo kunye neenkqubo zokuvavanya kufuneka ziphunyezwe. Ukusebenza kwe-insulation ngokuqhelekileyo kuvavanywa kusetyenziswa uvavanyo lombane ophezulu, imilinganiselo yokumelana nokugquma, kunye novavanyo lomjikelo we-thermal. Naziphi na iibhodi ezineziphene okanye iileya kufuneka zichongwe kwaye zilungiswe phambi kokuba kuqhutyekwe phambili okanye kuthunyelwe.

Ngokugxininisa kule miba ibalulekileyo, abaqulunqi kunye nabavelisi banokuqinisekisa ukuba ukusebenza kwe-interlayer insulation ye-PCBs ezininzi zihlangabezana neemfuno eziyimfuneko. Ukutyala ixesha kunye nezixhobo kukhetho olufanelekileyo lwemathiriyeli, uyilo lwe-impedance olulawulwayo, ubukhulu obufanelekileyo bokugquma, ulungelelwaniso oluchanekileyo, ukulawulwa kwe-lamination, kunye novavanyo olungqongqo kuya kukhokelela ekuthembekeni, ukusebenza okuphezulu kwe-PCB yamanqanaba amaninzi.

Isishwankathelo

Ukufezekisa ukusebenza kwe-interlayer ye-interlayer efanelekileyo kubaluleke kakhulu ekusebenzeni okuthembekileyo kwee-PCB ze-multilayer kwizixhobo zombane. Ukuphumeza ubuchule kunye nezicwangciso ezixoxwe ngexesha loyilo kunye nenkqubo yokuvelisa kuya kunceda ukunciphisa ukuphazamiseka komqondiso, i-crosstalk, kunye nokusilela okunokwenzeka. Khumbula, ukugquma okufanelekileyo sisiseko soyilo olusebenzayo, oluluqilima lwePCB.
